MACHINE 'FOR OPERATING 0N HEELS.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application led May 7, 1917. Serial No. 166,989.

inconnection with the accompanying drawings, is a specification, like reference char-- acters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon heels and is herein shown as embodied in the heel attaching machine of United States Patent No. 1,195,134, August 15, 1916, although its application is not limited to that or to any particular type of machine.

In certain classes of work, notably in attaching high heels to shoes or in attaching heels to high boots, it is of great convenience to the operator to have clearance between the opposed work engaging members of the machine. This facilitates rapid work by rendering it easy to place the boot upon the jack vor the heel in the holder. An object of the present invention is to improve the construction of heeling machines in the respects discussed. The desired results are secured by automatic movement between the opposed engaging members in a direction transverse to their customary direction of approach for clamping the Work, so that in work receiving position their work engaging faces are not only spaced as shown but are out of alinement with each other.

A feature of the present invention, accordingly, consists in the combination, with a heel engaging membery or abutment, of yielding means, forreXample a spring, tend-v ing to move said member horizontally to an inoperative position out of alinement with the jack, and means for locking the member againstthe action of the spring atthe limit of its horizontal path of movement. This locking function mayl advantageously be accomplished by an actuating mechanism of special construction operating first to move the abutment into alinement with the jack and then to lock it positively in that position.

These and other features of the invention machine.

will be best understood andl appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which- Figure 1 is a view in side elevation of portions of the machine of the patent above identified having the present invention embodied therein;Y

Fig. 2 is a view in front elevation of the head of the machine;

Fig. 3 is a detail of part of the operating mechanism for the movable heel engaging member.

The machine frame 2S as herein shown is provided with vertical bearings for a reciprocatory plunger 6, opposite to which is mounted a stationary jack Q6 in which the driver gang is located. The plunger 6 is operated by a lever 13 secured'to a transverse shaft 34 journaled in the head of the machine frame. A lever 32 is secured to the shaft 34 outside the frame and is connected at its rear end to a treadle operated formed upon the lower end of the plunger 6. A springV 19 connected to the base of the member 36 at one end and at the other to a bracket 20 normally holds the member 36 in its rearmost position. A stationary stop 21 is arranged to engage a shoulder 2Q, on the member 36 when the latter is moved forwardly, thus determining the operative position of this member.

Uponthe outer end of the shaft 341 is secured an upwardly extending arm 2 forked at its upper end and having a trans-v versely, freely rotatable pivot pin 3 extending through its forks. The pivot pin is bored to receive the end 0f a bar A which is adjustably secured to the pin 3 by a spring detent7 mounted in the pin 3 and shaped at its inner end to engage teeth 6 cut in one side of the bar 1. At its forward end the bar is supported by an eccentric stud 8 set in a bracket 9 secured to the head of the The forward end of the bar is beveled as shown in Fig. 1 and its positions may be accurately adjusted by turning the eccentric stud S.

The bracket 9 is provided with journals for a short transverse shaft 1l carrying at its outer end a cam arm 12 which extends downwardly into the path of the end of the bar el. At the inner end of the shaft l1 is secured a depending arm 1/-1- terminating in a long sleeve bearing 15. Free to slide in this sleeve 15 is a rod 1G the lower end of which has a hook engaging horizontal pin 1S at the front of the base of the heel engaging member 86. The member 3G is limited in its rearward movement by the engagement of the sleeve 15 with an abutment formed on the head of the machine frame.

rllhe parts of the machine initially occupy the positions shown in full lines in Fig. 1 from which it will be seen that the operator has convenient opportunity for placing` a longlegged boot upon the jack Q6. The treadle is then depressed, elevating the rod 3l and swinging the lever 32 and the arm rlfhe bar 4 is thus moved forvirardljv and its beveled end forced against the cam arm 12 swinging the latter outwardly and forwardly and turning the shaft 11. The arm l/-l is accordingly moved outwardly and the member 36 drawn int its forward position as shown by dotted lineasI in Fig. 1. The bar 11A is so adjusted with respect to the arm 12 that the latter is operated during the initial movement of the bar and during the continued movement of the bar the arm l2 rides upon its upper surface thus locking the arm 1st and the connected member 36 against return movement. 1t will be noted that the sleeve 15 and the rod 1C form an extensible connection between the swinging arm 14 and the sliding member 36. The continued depression of the treadle lowers the plunger 6 through the lever 13 until its movement is resisted by the work clamped between the two heel engaging members. Thereupon the treadle supporting arm 2f) is depressed and the power operated mechanism of the machine started as fully eX- plained in the patent above identified. The final downward movement of the plunger (l is caused by mechanism, not shown, operating on the lever 13.

After the operation of the machine the release of the treadle by the operator results in the parts moving` back to initial position in the reverse order. 1f is should be desired to render inoperative the automatic mechanism for moving the member laterally, t-he hook of the rod 16 may be disengaged from the pin 18 and the rod 1G held up in the sleeve 15 by the insertion through a hole in the rod of a cot-ter pin 2l.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent of the United States is:

1. A machine for operating on heels, having, in combination, al heel engaging member mounted to move vertically and horizontally, yielding means tending to move said member horizontally to an inoperative position, and means for locking the member against the action of the yielding means at one limit of its horizontal path.

2. A machine forv operating` on heels, having, in combination, cooperating heel engaging members one of which is arranged to slide transversely, a springtending to hold said member out of line with the other member, an arm for moving said member in opposition to the spring, and means for positively locking the arm in position with the spring under tension.

2l. A machine for operating on heels, having, `in combination, a reciprocatory head carrying a sliding heel engaging member, a lever for moving t-he head, and a bar connected to said lever and constructed and arranged in its initial movement to shift said member with respect to said head and then to lock said member in operative position.
